FAN ATTACHMENT FOR S NINGS..

Application filed September 21, 1921 Serial No. 502,233.

To all whom it may concern Be it known that I, HIRAM 'MoGnATn, a citizen of the United States, residing at Me- Connelsville, in the county of Morgan and State of Ohio, have invented certain new and useful Improvements in Fan Attachments for Swings, of which thefollowing is a specification.

This invention relates to for swings. 1 The object of the invention is to provide a simple and cheap device of thisfcharacter which is readily attachable to any swing and soconstructed that the swinging movement of the swin ives constant oscillation to the fan.

tan attachments Another object is to provide a fan of this character equipped with a hood for protecting the fan from the weather and also adapted to direct the current of air pro duced thereby down onto the user of the swing. I

With these and other objects in view, the invention consists in'certain novel features of construction as hereinafter shown, described and claimed.

In the accompanying drawing Figure 1 represents a front elevation of a porch swing equipped with this improved fan attachment,

Fig. 2 is a transverse section taken on the line 22 of Fig. 1,

Fig. 3 is a side view thereof with parts broken out for convenience in illustration, and, 1 Fig. i is an enlarged detail longitudinal section taken on the line 4 of Fig. 3.

In the embodiment illustrated a seat 1 is shown connected to the ceiling 3 by chains 2.

Mounted in the opposed chains 2 in the links thereof are journals 6 carried by the ends of a shaft 5. the chain links forming bearings for said journals. Mounted or secured near opposite ends of the shaft 5 are two pulleys 7 around which is wound fan operating cords 8. I

The shaft 5 and pulleys 7 constitute a part of the fan 10 which is mounted abovethe seat 1 and may be oi any desired construction being here shown in the form of a plurality of blades 11 radiating from the shaft 5 and terminating at points spaced inwardly from the pulleys 7, as is shown clearly in Fig. 1.

Two bars 9 extend laterally from a'support at the rear of the swing, here shown a a wall 4 and extend over the pulleys 7, said bars having loose connection with the wall 4 as shown at 12, to permit the swing to move laterally. Depending'from each bar 9 is a pair of coupling members 9. The cords 8 J are secured at their opposite ends to a pair of coupling members 9 on the lower ends thereof as is shown clearly in Figs. 2 and 3, and each cord is wound around the pulleys three turns to provide for the revolution of inserting the journals 6 in any of the links desired. j

A hood 13 is mounted above the fan 10 and is here shown substantially semi-cylin drical in crosssection with closed ends from whichproject longitudinally spaced Studs let-adapted to be inserted in the chain links above the fan to properly position the hood relative to the fan. This hood 13 not only protects the fan against the weather when the swing is located out of doors, but it also operates to impart greater force to the air currents produced by the fan and to direct them downwardly onto the user of the seat 1.

While a fan having four blades is here shown, obviously any desired number may be employed. In the use of this attachment when applied as shown in Fig. 1 of the drawing, the swinging movement of the seat 1 operates through the chains 2 and cords 8 to turn the shaft 5 andoscillate the fan 10 thereby producing air currents which are directed by the hood 13 down onto the user of the seat.

This attachment while very simple in construction and readily applied. to any or- -cally disposed swing side chains, of a pair of spaced parallel bars having means on wardly with respect to the journals thereof and arranged below said bar, a pair of spaced coupling members depending from each bar, and a pair of flexible members each connected at its ends to a pair of coupling members and wound intermediate its ends on a pulley whereby during; the Shifting of the chains a. rotative movement will be imparted to the fan shaft.

2; The combination with a pair of vertically disposed swingside chains, of a pair of spaced parallel bars having means on. their inner ends for loosely cornecting them to a support, said bars arranged between and extending at right angles with respect to said chains, a fan shaft arranged below and in wardly with respect to the outer ends of the said bars and provided with journals mounted in opposed links of said chains, radially disposed fan blades secured to said shaft,

pulleys attached to said shaft inwardly with respect to the journals thereof and arranged below said bar, a pair of spaced coupling members depending from each bar, a pair of flexible members each connected at its ends to a pair of coupling members and wound interminate its ends on a pulley whereby during the shifting of the chains a rotative movement will be imparted to the fan shaft, and a semi-cylindrical hollow protecting member arranged above and in proximity to said shaft and formed with closed ends, each of said ends provided with a pair of super posed studs extending into the links of a chain whereby said protecting member is held in position between said elements.

3. The combination with a pair of swing side chains, of a fan element interposed between said chains. opera. ing means for .jilti element connected with said chains, and a semi-cylindrical hollow protecting: member arranged above and in proximity to said ole ment and formed with closed ends each provided with a pair of superposed studs extending into a pair of links of a chain for securing said member in position between the chains.

In testimony whereof, I atlix my signature hereto.

HIRAM McbrRATH.
